For the past $12$ years, George Link has operated his appliance repair business out of a $1,000-$square$-$foot, ground$-$floor office in a four$-$story commercial building called $129$ Main. Last year, George signed a five$-$year lease with Kramer Management, the owner of $129$ Main. This year, Kramer decided to convert the building into condominiums and is negotiating with all its tenants to surrender their leasehold rights and vacate their space in $129$ Main. Kramer has offered George a $$50,000$ cash payment and the use of a $1,200-$square$-$foot office in a new shopping center recently constructed by Kramer. If George accepts Kramer$$s offer, he can use the new office rent free for $36$ months. The fair rental value of this office is $$1,300$ per month. What are the tax consequences to George if he accepts Kramer$$s offer and moves his business location?
